    This article presents a unique point of view for microstrip reflectarrays. Through the effective utilization of graphical visualization of the scattered fields from the reflectarrays, one can gain insightful understanding into the fundamental workings of these antennas. The most important part of the reflectarray analysis and design is the accurate characterization of the individual reflectarray e... View full abstract»

  • Electromechanical Coupling Analysis of Ground Reflector Antennas Under Solar Radiation

    The surface-accuracy design criterion for the next-generation reflector antennas for the deep-space instrumentation project in China was 0.1 mm rms. However, these antennas have no radome or air-conditioned ventilation to protect against solar radiation. Therefore, the effect on the antenna's electromagnetic performance of thermal deformation due to solar radiation must be carefully evaluated. For... View full abstract»

    Although inflatable antennas represent a new and untested technology for remote-sensing applications, the advantages of small volume, low cost, and low mass provide an incentive for people to invest in developing this technology. The space-borne inflatable antenna concept was evaluated for passive microwave sensing of ocean temperature, wind, and precipitation. A large-diameter (3 m), on-axis, par... View full abstract»

    A survey of electromagnetic integral-equation solvers, implemented on graphics processing units (GPUs), is presented. Several key points for efficient GPU implementations of integral-equation solvers are outlined. Three spatial-interpolation-based algorithms, including the Nonuniform-Grid Interpolation Method (NGIM), the box Adaptive-Integral Method (B-AIM), and the fast periodic interpolation met...

    Efficient analysis of electromagnetic-wave responses from electrically large complex objects is a crucial but difficult topic in many applications of electromagnetic engineering. Among various numerical methods, the Method of Moments (MoM) solves for surface- or volume-distributed equivalent currents, which are expanded in terms of basis functions. In this paper, the traveling-wave phase variation... View full abstract»

  • Joint Time-Frequency Analysis of Transient Electromagnetic Scattering from a Subsurface Target

    The complexity of transient electromagnetic scattering from objects in free space has been well known for years. Such complexity is mainly due to the high aspect dependency of the early-time response, and the interactions between the various scattering events. Attempts have been made to analytically and numerically study the transient scattering problem using time-frequency (TF) analysis. Using th... View full abstract»

    Since the article by K.T. Selvan, "Fundamentals of Electromagnetic Units and Constants" (IEEE Antennas and Propagation Magazine, Vol 54, no 3, June 2012, pp. 100-114) appeared in print, two relevant previous papers have come to the author's attention and are note here. Leo Young's article (2002) presents an interesting discussion, with examples, of conversion and comparison between different syste... View full abstract»

    This paper presents an integrated approach to taking a frequency-domain simulation problem into the discrete time domain, based on z transforms. The ideas are illustrated with free space, the Drude pole, and perfectly matched layer (PML) conversion examples, for both leapfrog time stepping and simultaneous time stepping. Numerical results for various perfectly matched layer methods are given. We t... View full abstract»
